Introduction to Data Science

Course Description

This course introduces the students to five key facets of a data-based research: (1) data wrangling, cleaning, and sampling to obtain a suitable data set, (2) data management to facilitate efficient access to big data, (3) exploratory data analysis to generate hypotheses and intuition, (4) prediction based on statistical methods such as regression and classification, and (5) communication of results through visualization, stories, and interpretable summaries.

Learning Outcomes

  1. Use Python and other tools to scrape, clean, and process data
  2. Use data management techniques to store data locally and in cloud infrastructures
  3. Use statistical methods and visualization to quickly explore data
  4. Apply statistics and computational analysis to make predictions based on data
  5. Describe the outcome of data analysis using descriptive statistics and visualizations
  6. Use cluster and cloud infrastructure to perform data-intensive computation
